instanceof Java Keyword Tutorial #90

The instanceof keyword returns true if what's on the left is a class, subclass or interface of what's on the right. Like this:

someObject instanceof someClass;

This lets you quickly check if an object is related to another class or interface! I honestly don't use it very often, but it can be very helpful for certain situations.

I hope you enjoyed this instanceof java tutorial!

It's funny... I literally looked this up on Google a couple of hours ago to see if there was some keyword in Java that did this.

[geofflovig]

nice work. Instanceof is useful when using several implementations of an interface or class. if(instanceof Eagle) “screech“ else if (instanceof canary)”sing”.
